Wireshark Display vs Capture Filters

A common thought by beginner Wireshark users is that display and capture filters do the same thing. Well, they don’t; they may seem to be doing the same thing to you but the difference is when the packets get filtered.

Display filters don’t stop Wireshark from capturing any packets, you still capture all packets but it only displays you the packets you asked for. While capture filters when used make it so Wireshark won’t capture any packets that you have specified not to.
